首先需要创建一个数据源，SSAS（分析服务）将利用数据源来连接源数据库。
一、准备环境
1. 准备SQL Server
安装一台SQL Server 2012。
2. 安装DEMO数据库
下载一个演示数据库 。本实验用到的数据库为：
AdventureWorksDW2012 Data File
application, 206080K, uploaded Mar 12, 2012
3. 准备SSDT
从 SQL Server 2005 起，SQL Server将商业智能的开发功能统一到一个工具，，称为BIDS（Business Ingelligence Development Studio）。在SQL Server Denali CTP3时称为SSDT（SQL Server Developer Tools），SQL Server 2012 将其重新命名为SSDT（SQL Server Data Tools）。
这个SSDT工具实际上就是Visual Studio。安装 SQL Server 2012 时，如果本机没有事先安装 VS2010，那么 SQL Server 2012 安装程序会在本机安装一个 VS2010 的 partner 版本。
二、启动SSDT，新建项目
启动SSDT，实际上是启动了VS2010，然后利用“商业智能”模板来创建和管理一个BI解决方案。
三、创建数据源
对于数据源的概念，可以将其简单理解为类似于ODBC设置数据源的功能。
测试连接，如果正确连接到数据库，则出现以下信息：

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AMThe best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
